We all are aware that the function of air conditioner units during the hottest days (summer season from April to October) is going to be one of basic needs. Therefore it’s important to prepare your unit to get ready to face and through unfriendly extreme hot weather as well. Good preparation not only will help you to enjoy the summer months satisfactorily but also helpful to save your money on the high air conditioning costs that usually you must pay for each month because your unit is already prepared on the best efficiency performance.
There are some different frequently problems when using air conditioning appliances such as Freon leaks, water drips, and too older units that usually no-longer to work optimally. And in this posting, let’s explore more about factors that can make older air conditioning units fail to work! When your ac unit is getting a little older then usually you will start to find some problems that basically indicate your ac cannot run optimal, efficiently, and powerful to cool the air in your room. If you find these unfriendly circumstances; perhaps it’s the right time to start considering a replacement. Although some experts recommend to avoid using older units (more than six years) but by doing little maintenance you can still get occasion through few months more with your old ac units as well.
There are several top factors and reasons why older air conditioning units fail or cannot work optimally. Let’s discuss about those factors below;
The first point is about refrigerant leaks:
Normally, air conditioner’s coolant performance will drop after several years of use! This problem can be caused with two popular factors; dirty air filter and refrigerant leaks. What the factors that cause and result refrigerant leaks? Environmental damage, vibration, changing temperature periodically (when unit running), etc will make the reliability of seals and joints in the coolant decrease that eventually fail and result refrigerant leaks.
Why refrigerant leaks will make air conditioner cannot cool the air optimally? Losing of refrigerant coolant will make unit run too cold at coil’s evaporator! It will stimulate coil icing process and finally the system will lose of cold air to distribute into the room (not powerful to cool the room). This problem will not be solved completely by simply adding with more coolant. Wrong recharging either undercharged or overcharged will make the system cannot get at top efficiency when running that eventually will consume energy wasteful and you will lost much money due to the high energy bill.
Therefore, by contacting a professional technician or HVAC contractor in your local area is more recommended! A service technician will recharge system with the level coolant specification accurately.
Caused by electrical problems:
The electrical failure can make the ac fails to work! You should know that the mechanical system of your ac unit can be categorized as object to tear and wear easily. Fan and compressor are example of some mechanical parts that easily wear out, particularly if the ac unit turns on and off frequently. The wrong size (especially lower size which the large space of the room is too large) is the dominated factor why unit could turns on and off not normally.
Therefore, don’t miss to check terminals and wires regularly. Ensure both free from corrosion! For the better result, by hiring a technician to check the electrical contacts and connections regularly is smart idea and so recommended.
Hard and noisy compressor:
Too old compressor usually will hard to run and noisy. Too low voltage supply is also can lead to incorrect compressor operation. Hard and noisy performance can be used as indication that compressor is near or at the end of its life. Bad performance of compressor cannot compress the reversion refrigerant gas to an adequately high pressure properly that eventually will lead to lose of cooling output or even can make the system fails to work.
The other problems that make your older air conditioner cannot work properly:
- Dirty filter that can lead to lose cooling capacity and result not-clear cool air output. It is also familiar known as clogging problem.
- Bad performance of blower fan (not moving sufficient air) which finally will make ac unit works not optimal such as too cold or too warm (if you use HVAC model).
- Too high BTU size or over size. Unfortunately some people have the wrong assumption that as higher size is good point to get and guarantee the air conditioner will work quickly when cooling the room. It is absolutely wrong, over size will make unit works inefficiently and cannot dehumidify the room adequately.
Those problems that have already been written can be minimized by doing the proper maintenance. If you are people who so busy and don’t have time to check regularly your air conditioning system then why not to get and sign a contract with a professional service to ensure your existing ac units get the proper maintenance as well.
